Now consider the simple network below, with sender SRC and receiver RCV. There are two routers, R1 and R2.
SRC------- R1------ R2------ RCV
For simplicity assume that the queueing delay and processing delay is zero at both R1 and R2. The distance between SRC and R1 is d0 meters, the distance between R1 and R2 is d1 meters , and the distance between R2 and RCV is d2 meters. Assume that the propagation speed on all links is 2.5 x 10⁸ m/s. Each traceroute packet is 50 bytes. The RTT delay to R1 as reported by traceroute is always 12 ms, the RTT delay to R2 as reported by traceroute is always 36 ms, and the RTT delay to RCV is reported by traceroute is always 76 ms. What is the transmission rate of all three links (SRC-R1, R1- R2, R2-RCV)?
